DEBIAN-CVE-2026-48045

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.12, AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query, each up to MAXMSGABSOLUTE = 8966 bytes, in self.deferredaddr and armed a per-address timer in self.timersaddr without...

CVE-2026-47184

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.7, DNSCache.asyncadd inserted every response record into cache, expirations, expireheap, and servicecache without a cap, allowing unauthenticated hosts on the local link over UDP/5353 224.0.0.251 / ff02::f...
